Zhang Zi'an has sometimes dreamed of the nameless German headland these days, dreamed of those dense strange sea creatures, and even created even weirder creatures in his dreams.

The unfathomable depths of the ocean are filled with creatures that challenge the boundaries of human imagination, and once these creatures are all attracted by Shihua's presence in Marina City, it is hard to imagine what the consequences will be—sharks, whales, and king squid will gather in the harbor, and it may cause a big commotion.

It's comparable to a weapon of mass destruction!

Therefore, Zhang Zian is very concerned about the answer to this question.

Shihua shook her head blankly, indicating that she didn't know.

Obviously, her ability to summon sea creatures is one of her passive skills, probably because of her characteristic phrase "to make the scales think and come to sleep with her" - because she is so beautiful that many sea creatures are unconsciously attracted to her and want to sleep with her.

Zhang Zi'an scratched his head, what can I do?

Shihua didn't know the seriousness of the matter at all, and hummed his own children's rhyme to play with the little yellow duck.

"A little yellow duck, two little yellow ducks, swim to see Oba, Oba is not at home, come back to find Shihua ......"

"Quack!"

Richard flew up from downstairs with fluttering wings, and just happened to hear him speak, so he interjected: "You idiot! Don't you forget? Didn't she sing a song and sing that white whale away! According to Uncle Ben's opinion, you should have brought that white whale back at that time and rode it to meet the island actress you longed for, just in response to that sentence - Fusang will ride a whale on this day, and Zi'an will turn into a crane in what year!"

Zhang Zi'an picked up the soap and threw it over, "Your uncle's!

"Quack!" Richard cleverly dodged, and flew downstairs to tease the other elves, and its noisy voice could be heard from the stairwell in the distance—"Throw soap on your head and bend over to offer chrysanthemums!"

As soon as it left, the second floor suddenly fell silent.

Zhang Zi'an pondered carefully, what it said was quite reasonable, of course, it didn't mean to lean over and offer chrysanthemums, but that the beluga whale left the coast and returned to the deep sea after listening to Shihua's singing, which showed that although she couldn't control the sea creatures and let them not follow, she could let them leave.

"Shihua, when you were on the coast of Germany, you sang a song to that beluga whale, didn't you? and then the beluga whale left?" he asked.

"Uh-huh. She nodded absent-mindedly.

"Then can you do the same and let the sea creatures that are approaching Marina City leave?"

She nodded and shook her head, "It's too far away to hear." ”

"Do you mean that if the sea creatures are too far away, they won't be able to hear your song?" he asked again.

"Hmm. ”

Well, he didn't think about that.

If Shihua can leave the pet store and go to the sea or the beach to sing, it will be fine, but she can't leave the pet store for the time being......

Why don't you try recording her singing and then go to the beach to show it?

But this can't be done, even if you go to the beach and put it, how far can it be spread?

Zhang Zi'an couldn't think of any other way to bring this mermaid to Binhai City, but he didn't expect it to cause such a big trouble.

He was about to go downstairs for a walk, hoping to come up with a solution, when he heard Shihua mutter, "If Oba hears my singing, will he come here to find me......

"Impossible. Zhang Zi'an dispelled her thoughts as soon as possible, "Isn't your Oba in South Korea? It's hundreds of kilometers away from South Korea!"

She pouted, "Hundreds of kilometers? How far is a few hundred kilometers?" and I could hear the whales crying in that direction. ”

As she spoke, she raised an arm and pointed in a north-easterly direction.

Hey?

Zhang Zi'an was stunned and looked in the direction she pointed, but could only see the wall of the bathroom.

"Wait, what do you mean?" he asked, "do you hear the whale crying? From here, you can hear the whale crying? Why can't I hear it?"

"Because you're stupid! Didn't that bird call you an idiot!" she grimaced at him.

Zhang Zi'an was in no mood to joke with her, and asked seriously: "Shihua, please answer me seriously, can you hear the whale now?"

Shihua rolled his eyes slyly, "Is there a reward for answering?"

"Yes, of course. He replied casually.

"What's the reward? I'm going to watch TV!" she said excitedly.

Zhang Zi'an thought for a while, "I can promise you to shorten your waiting time, but it is impossible to watch TV right away, because there is only one TV at home, and now the old man is watching it." You see that the old man is old, let's respect the old and love the young, right?"

"Is that the old brown cat that dressed me?" she asked childishly.

"Yes, it's called Old Tea, you can call it Old Man Tea like me. Zhang Zi'an replied.

She was reluctant, but reluctantly agreed, "Then what do you say?"

"Of course it counts. He agreed, "Now answer my question." ”

"I can hear it, not just the whales over there, but over there, over there, over there, and over there!" she said, waving her finger around almost 180 degrees from 2 o'clock to 7 o'clock, with a serious expression that didn't look like a joke.

Zhang Zi'an understood.

Humans have a vocal range of 2 to 3 octaves, while whales have a vocal range of 8 octaves, and they can emit murmurs that are inaudible to high-frequency scales that almost pierce the eardrum.

The speed at which sound travels in the air at room temperature is 340 m/s, while in the sea it travels at a speed of up to 1500 m/s.

Whales use their low-frequency sound waves to communicate over long distances, and are even able to send simple signals to their whale companions thousands of kilometers away.

Low-frequency sound waves alone are not enough to cover such long distances, and whales are able to do this because of the "deep sound channels" in the oceans. The so-called deep sound channel is actually a water layer with different densities, which has the characteristics of guiding sound waves due to the density difference between the water layers, but this deep sound channel is only open to low-frequency sound waves, which is an exclusive benefit for whales.

The sound signals of whales are very complex, and the sounds produced by different species of whales are also different, and even the same whale will have a unique regional accent because it lives in different areas, just like humans.

Are they singing endlessly in the sea, talking to each other, or humming a little song to their own amusement? Despite a lot of research done in recent years, humans still have no way of knowing.

Shihua said that she could hear the whales, and pointed in the four directions of the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea, which means that she can hear the low-frequency sound waves emitted by the whales in the surrounding waters, which may be the privilege of being an elf.

As soon as he figured out this question, he immediately asked in surprise, "Shihua, why are whales crying?"

"I don't know......," she shook her head in confusion, "I just know they're crying." ”

Although low-frequency sound waves travel extremely long distances, they carry a very low amount of information, only 1 bit per second. In comparison, each word carries 10 bits of information when a human speaks.

So Shihua didn't lie, nor did she mean to prevaricate, but she could only hear the whale crying, but she couldn't know why she was crying.

Maybe after a while, new information will come in.

Sure enough, she listened to it again and said, "The sound is very chaotic, they seem to be running away, like they are being chased, and they are being ...... Kill ......"

At this, she looked frightened, and a fine layer of goosebumps appeared on her fair, smooth skin with shivers.

"Forget it, don't listen to it, I've got it. Zhang Zi'an interrupted.

She stared at him suspiciously, her mouth half-open, expecting his explanation.

"It's whaling, and there may be people in South Korea who are secretly hunting whales. Zhang Zi'an sighed, "This is obviously a violation of international conventions, but ...... It's hard to stop it completely. ”
